Chapter 1: Q9 (page 10)

Determine whether the sampling method appears to be sound or is flawed.

Nuclear Power Plants. In a survey of 1368 subjects, the following question was posted on the USA Today website: 鈥淚n your view, are nuclear plants safe?鈥� The survey subjects were Internet users who chose to respond to the question posted on the electronic edition of USA Today.

Short Answer

Expert verified

The sampling method is flawed.

Step by step solution

01

Given information

  • The survey question enquires whether nuclear plants are safe or not.
  • The number of subjects who took the survey was 1368.
  • The respondents were net users who self-participated in the survey. The question of the survey was published in the electronic edition (website) of USA Today.
02

Explain the sampling method

The survey comprises the responses from subjects (participants of the study) who volunteered to answer the questions on the internet. Thus, the sampling method is volunteer sampling.

Moreover, the responses were taken only from those readers who read the electronic edition of USA Today.

03

Explain if the sampling method is flawed or sound

The volunteer response sampling is a biased method as the subjects do not represent the entire population.

The sampling must be done randomly to derive accurate results in the study.

Thus, the sampling method is flawed.

Discrete/ Continuous Data Which of the following describe discrete data?

a. The numbers of people surveyed in each of the next several years for the National Health and Nutrition Examination Surveys.

b. The exact foot lengths (measured in cm) of a random sample of statistics students.

c. The exact times that randomly selected drivers spend texting while driving during the past 7 days.

Identify whether the given value is a statistic or a parameter.

Periodic table The average (mean) atomic weight of all elements in the periodic table is 134.355 unified atomic mass units.

Correlation. One study showed that for a recent period of 11 years, there was a strong correlation (or association) between the numbers of people who drowned in swimming pools and the amounts of power generated by nuclear power plants (based on data from the Centers for Disease Control and Prevention and the Department of Energy). Does this imply that increasing power from nuclear power plants is the cause of more deaths in swimming pools? Why or why not?

In Exercises 29鈥�32,identify the level of measurement of the data as nominal, ordinal, interval, or ratio. Also, explain what is wrong with the given calculation.

Temperatures As this exercise is being written, it is 80oF at the author鈥檚 home and it is 40掳F in Auckland, New Zealand, so it is twice as warm at the author鈥檚 home as it is in Auckland, New Zealand.

Statistical Significance and Practical Significance. In Exercises 13鈥�16, determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

Gender Selection In a study of the Gender Aide method of gender selection used to increase the likelihood of a baby being born a girl, 2000 users of the method gave birth to 980 boys and 1020 girls. There is about a 19% chance of getting that many girls if the method had no effect.
